Man thats cool! Love the concept :D

Lovely idea. I think that the lighting could be worked on a little and maybe a more balanced pose.

Thanks again :)

I think a bit of soft shading on the inner outlines would look good. I like it overall though ,especially the brain area itself, the colors on it blend well. : D

One of your better pixels, Framin.  Nice work. 

Awesome design, I love that head!

Gas that edit is super sexy.

Great concept! It does look a bit rough, is it unfinished?

Gas said it all for me. Its a good pixel tho :)

I like the colors and design, this type of person is my favorites for pixelarts...
Nice Work Framin!

Gas 13: thanks for overpaint. It now looks TOO metllic for me, but i undestand what you mean :)

Thanks for useful critics, guys :)

Quick edit to show what I mean.

Nice design, but you should pay more attention to colors, IMHO
Love how you did the hands.

That's interesting. Several things I would suggest:

1. Avoid dark inner outline. If it's not a style matter (and looks like it's not here) you should not keep that outline.
2. Looks like you were going to make the details metallic. It's great that you add reflexes on the metal but the next thing you should do is adding contrast between highlights and shadows.
3. Double pixel outline, inaccuracy.

It's easy to see you have a good potential. Keep it up.

Brain needs more contrast shadows as for me
